My invention relates to envelopes, wherein it is desired to provide an envelope particularly adapted to aconstruetion to simplify I the manufacture,'and to assist the'user of the p l envelopes in sealing the same without tearing the envelope at the sealing flap, and more in providing an extremely simple construction for an envelope. A feature of the invention resides in providing an envelO lope particularly adapted to that class of'en-- velope used for mailing matter, so .that first.

classmail can be'carried along with other mailing matter of another class. This per-;; m1ts mail having an analogous relation to be 16 sent out together and received at the same time by the party to'whom it is addressed.

, An importantfeature of my invention resides in the particular formation of the died out blank of the envelope which permits the 20 necessary flaps tobe cut out without waste of material and without projection of the flap for one of the compartments of the envelope. l he non-projecting flap of the died out formation'of this envelope is out along 'of the envelope, so that an envelope died out of the'formation I have illustrated can be more readily and easily handled in folding and pasting the same, thus permitting these envelopes .to be made very rapidly 'on machinery. designed to handle thesame.

It is also a feature of my invention to pro-, 'Jvide an envelope wherein the non-projecting flap is made along the marginal edge of the overlap of the envelope, which forms one wall of the envelope, by notchlng out a portion of the marginal edge to provide a space between 1 the flap and themaiginal edge which is pasted down. This space is very important, because it permits'the portion of themargin which is pasted down to form the, overlap to be at.- tached securely or pasted, without pasting I the fla'pfor the edge thereof, as the flap is spaced-away from the edge of the margin, which is pasted down sufliciently to prevent any possibility of the pastin of the unprojecting marginal flap, and t ereby perm1tting my envelope to be made up'very-rapidly. My invention constitutes the notching out ing to the depth of the cut the marginal edge of the overlap of the sides located, This Second compartment i (3011' of a marginal nonprojecting flap, the'notchedout portion having rounded or arcuated cuts to prevent any sharp corner or pointed cuts,

which would cause the flap to easily tear at the depth of the out. In other words, the depth of the cut is rounded to strengthen the flap, and prevent the same'from easily tearwhich is necessary to make the same.

7 Further, this form of notchin out the marginto form a flap for the enve ope provides an envelope which maybe used for two classes of mailing matter, the non-projecting flap acting as'the closing flap for one class of mail matter, while theiordinary projecting flap may be used to close the other compartment of the envelope.

- Bynotching out a portion of the marginal edge, I also provide an indicationto snow Where the compartment which is formed on the side wall of the envelope for mail matter is located, and by printing acolor on the envelope, this notched outfportion is'very clear 1y indicated, and is provided to show where the second compartment of the envelope is siderably smaller thanthe-main portion of I the envelope, thus it is quite an advantage to construct the envelope in the died out formation which I have illustrated,

;These, and other features,together with details of the invention will be hereinafter more fullyand clearly set forth:

In the drawing forming a part of this specification:

Figure I is a side View of my envelope folded correctly. Figure 2 is a section'on the line 22 of Figure 1.

Figure 3 illustrates the died out or geometric development of my envelope in its proper form.

Figure 41. illustrates my envelope folded and the closing flap for the compartments sealed and folded in to enclose the contents .within the compartments of the envelope.

. In the drawing, my envelope A is of a very simple nature, and is adapted-to be cut out of v a sheet of paper in the died out formation illustrated in Figure T e died out formation of my envelope inenvelope A, while the flap 12, which is of aor narrower width than the flap 11,1s

shorter adapted to be folded on the line 14 over on to the flap 11. V 1.

Flap 12 provides the marginal edge 15 of the overlap of the envelope A and has amarginal portion 16 of paste or glue together with an inwardly projecting portion of paste '17,extending from the marginalportions of paste 16 toward'the folded l1ne-l4 as lliis-- trated in Figure 3. Thus, when the flap 12 is folded over on to the flap 11, the glue por-f tions 16 and 17 are adapted to be secured to the fla 11." The inwardly projecting por tions 0? paste'17 are spaced apart to provide a central portion 18 in the flap 12 which is adapted to constitute one wall. of a compartment for the envelope A. The-other wall of this compartment is formed by the inwardly projecting free end of the flap 11 Thus a compartment for mailing matter is formed which is separated from the main compartment formedby' the center portions 10 and etheoverlying flapll.

I provide a marginal non-projecting clo-' sure flap 20 for the portion 18.0f envelope edge 15. .The'notching outportion '21 is formed with arcuated cut -"ortions at 22 so that the depth of the out o the notched out portion 21-is rounded and'thereby prevents tearing of the flap 12 at this point when it is 1n use.- v Y The flap 20 is adapted tobe'a pasted marginal surface'2%l 'while the center portion 18 may be formed with a window or" address opening 25 which may be coveredby translucent tissue paper or other suitable material,

' forms of envelopes.

' 1 profit it is necessary that they should be made on an envelope machine, that is they should" edge 15 and the pasted surface 24 of the 010- or may be left open as in the case of some It is important to note that the manufacture of envelope A,that to make them a be pasted and folded on a machine. Theretore the notched out-portion 21 is otgreatlmportance in my inventionas it provides a space betweenthe paste 16 of the marginal sure flap 20." .By providing this space, I preof the closure flap 20 in the-menu acture of these, envelopes A and the flap 20 may be-prothe portion18 in the flap 12. p

a. osite side of the.

edge on eitherside of extreme importance 'in my invention as it provides a closure flap for the compartment of my envelope A which may be used for first class mail matter, and this type of envelope cancarry the one address visible through the opening 25 with the added advantage of carrying-twoclasses of mail matter at difi'ercut rates of postage.

I provide a short end flap 26 which is adapted to be folded and pasted down on the flaps 1-1 and 12 to close one end of the compartment of envelope A, and on the other end.

of the envelope A, I provide a longer flap 27 which may be tucked in as illustrated in Figure 4,'to permitexaminatien' eithecom ,tents of the large portion'of the envelope.

The notched out portion 21 forms an indieating space so as to readily indicate a separate envelope flap for the portion 20, and by printing a colorsuch as 28' on a portion of flap 11.

' A distinct indication can be made apparent on-the envelope to clearly'show, even when the flap 20 is sealed as infigure 4, that another compartment. is" situated in the envelope A. By cutting out the-notch 21, the non-projecting fiap 20 maybe more easily engaged and sealed, so that together with the spacing of the respective edges of the margin 15 and the end edges of the flap 20- away from each other, I provide an envelope structure wherein a non-projecting flap may be used with a very distinct advantage, which ma I be read- A- ily appreciated in the envelope in ustry and by notching out portion 210i the marginal art. I I

In accordance with the patent statutes I" have described the principals of operationsides adapted to form one wall of the envelope and a non-projecting closure flap formed in the marginal edge of one of the sides, said nonprojecting flap being constructed by cutting away ortions of the marginal edge to permit sealing the mar a1 said flap with sai flap unsealed.

2. An envelope including overlapping side flapsconstructing one wall of the envelope, a compartment formed in the said .wall .withthe overlapping sides, and anonvent the accidental pasting of an portion projecting marginal flap formed by notching at thecorners and "depth of-the notched out portions.

3. A two compartment envelope including a main body portion forming one compartment, overlapping sides adapted to form one wall of the main body compartment, a. compartment formed by the overlapping sides therein; and a; non-pro ecting marginal having end portions spaced by an open portion from adjacent portions of the margi of the overlapping flap "OSCAR J. 0m.
